Problems solved by technology

These surfactants typically exhibit the disadvantage, however, of penetrating and potentially irritating the skin, eyes and scalp and generally giving a poor skin feel.
Furthermore, the use of conventional surfactants to manufacture emulsions typically necessitates the application of heat during processing, which can also be disadvantageous, in that it can restrict the ability to include heat-sensitive ingredients and in that it may also limit the types of place in which the manufacturing method may be performed—safety and other concerns, may, for example, prohibit manufacturing the emulsions in certain desired locations.
Another disadvantage of traditional surfactants, including alkoxylated surfactants, is that they may cause materials to re-emulsify after the emulsion breaks—emulsion breakage allows delivery of emulsified materials, but re-emulsification, such as after application of a personal cleansing composition to the skin during washing / showering, may reduce the desired benefit (because emulsified emollients and actives are washed off the skin in this example).
A further disadvantage of conventional surfactants is their inability satisfactorily to emulsify polar oils—many perfume oils fall within this category.
The exemplified emulsifiers are ethoxylated materials however, which suffer from the problems discussed hereinabove.

Perfume Gel

Concentrated Oil-In-Water EmulsionMaterial% wtWeight (g)EZ Sperse2.525Water17.5175“Electric Youth Plus”80.0800Fragrance Oil

Electric Youth Plus fragrance (a combination of perfume oils) has a dielectric constant of 7.40.

Procedure to Make the Concentrated Oil-In-Water Emulsion

The EZ Sperse and 7.5% wt water were mixed using a Kitchen Aid Ultra Power Mixer until uniform. The fragrance oil was then added at a rate of 8 g / minute while continually mixing with a Kitchen Aid Ultra Power Mixer having a paddle attachment at a setting of “4”. Due to the high viscosity, the emulsion was then diluted with the remainder of the water while continually mixing with a Kitchen Aid Ultra Power Mixer having a paddle attachment at a setting of “4”.

Abstract

In a first aspect, the invention concerns oil-in-water emulsions comprising defined water-soluble emulsification polymers and having an oil phase comprising polar oils. In a second aspect, products, such as cosmetic products, are provided, comprising the emulsions. In a third aspect, a manufacturing method is provided for making the products.

Description

FIELD OF THE INVENTION The present application concerns oil-in-water emulsions having a polar oil phase emulsified by non-alkoxylated water-soluble emulsification polymers. In a second aspect, products, such as cosmetic products, are provided, comprising the emulsions. In a third aspect, a manufacturing method is provided for making the products. BACKGROUND OF THE INVENTION Emulsions are generally stabilised by appropriate emulsifying surfactants, which, by virtue of their amphiphillic structure, reside at the oil / water interface and thus stabilise the dispersed droplets. These surfactants typically exhibit the disadvantage, however, of penetrating and potentially irritating the skin, eyes and scalp and generally giving a poor skin feel. Furthermore, the use of conventional surfactants to manufacture emulsions typically necessitates the application of heat during processing, which can also be disadvantageous, in that it can restrict the ability to include heat-sensitive ingredient...
